Question:

I have a 2025 Toyota Tundra SR5 4x4. Stock height in the rear, front added Bilstein 5100 w/2inch lift. Q1: How do you compare this PB62RV that I just purchased from you to Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers - Rear Axle Part Number: AL24JQ? Q2: Do any of the mentioned above air bag systems add ride height? Im towing a car hauler 5400 lbs TW 750 lbs using Weigh Safe WDH just installed, Test tow 5miles with Timbren, still sag 3/4inch so removed them since it didnt help so Im hoping the air bag will help. I just need to know once I install the air bag with trailer loaded and add air pressure to them as needed. Now after I disconnect the trailer and remove the air pressure from the air bags, will my truck add ride height or will it go back to stock height? Please look at the pictures and let me know if you think I even need the air bag system? I may want to return them if you havent shipped them yet. And just keep the Timbren. These pcitures are with Timbren and Weigh Safe WHD. Please advise.. Thank you, Scott

Hey Scott!

The air bags will have a slight impact on your ride height even when deflated down to the minimum of 5PSI they need to be to prevent them from collapsing. They will only rise your truck about a 1/2" or less. Have 3/4" of squat is usually safe to have. If you want to get closer to level, if possible, move your car very slightly back, it really wouldn't take much for it to affect how much weight you have on the tongue weight.

Your question about part # PB62RV that you just purchased vs part # AL24JQ. The internal jounce bumpers will affect your unloaded ride. I wouldn't recommend those if you're concerned about your unloaded ride.

Hi Gwendolyn, Thank you for answering my questions.. good advice! I will contact Brieann (from your support team) who I've been in contact with regarding the return policy and other questions - Brieann has been great and you as well Gwendolyn. I appreciate both of you answering all my questions so far. One other question: Which air bag system do you recommend that will be best for my need?.... knowing that I am concern about leveling my truck while towing and of course not adding the ride height when not towing is important too. Thank you in advance... Scott

@ScottS Brieann is awesome! I know she'll be able to help answer all your questions about a return. For my recommendation, I'd honestly say to go with the Air Lift kit without the internal jounces, part # AL84JQ. We only have just recently started to carry Pacbrake air bag kits so I don't have as much experience as I do with the Air Lift kits. Air Lift has really great fittings and air lines that I have found to be superior than some others out there.

@Scott I'm sorry to hear that she didn't get back to you. I saw that Lauren got some return information to you for the Pacbrake. Hopefully you will get the Air Lift kit delivered quickly so that you can get back n the road and towing! Let me know if you need anything else, Scott.
